Answer:
A rational number is a number that can be express as the ratio of two integers.
Step-by-step explanation:
Answer: A. 4.79(n)=20.00
Step-by-step explanation:
we need to find what amount of coffee (per pound) is equivalent to $20.00
so we take the unknown amount (n) and multiply it by $4.79
for example, say Ken wants 4 pounds, we need to know if it is equivalent to $20.00
so take 4.79 and multiply it by 4 to see if it is equal to or less than $20.00 in this case $4.79 x 4 = $19.16

Answer:
(x1 + x4)/2 = 4
Step-by-step explanation:
(x1 + x2+ x3 + x4)/4 = 5 mean
x1 , x2 , x3 , x4
median (x2+x3)/2 = 6
(x2+x3) = 12
The smallest integer is x1, the largest integer x2.
The mean of the largest and smallest of the integers is (x1 + x2)/2.
(x1 + x2+ x3 + x4)/4 = 5
x1 + x2+ x3 + x4 = 20
x1 + 12 + x4 = 20
x1 + x4 = 20 - 12
x1 + x4 = 8
(x1 + x4)/2 = 8/2
(x1 + x4)/2 = 4
